I recently viewed a question where the only answer was simply telling the OP to use a provided API instead of scraping data themselves.
Is this considered an appropriate answer on Code Review? My initial reaction was that it is not. It isn't reviewing code that the OP posted; it's simply mentioning an alternative (although I'll admit, better) way of going about things entirely.
It's upvoted though, so maybe I'm in the wrong in my thinking?
Should I mentioned to the answerer that their answer should be a comment? Should I just leave it alone?
